Data Sheet Glossary - Characteristics

 

Insulation Resistance

(Initial Insulation Resistance) The electrical resistance measured by applying a DC voltage of 500V between two elements of a component that are insulated from one another as measured at the final production test.

Dielectric Strength

The voltage value when within the speculated time, the conductors insulated with insulated material are applied to the voltage and the leakage current is less than the speculated current. The certain voltage above generally is the effective value of AC voltage and unless otherwise stated, the leakage current is generally less than 1mA.

 

Dielectric Creepage

The shortest distance along the surface of the insulating material between conductive parts according to IECC 61810-1.

Ambient Temperature

Temperature(s) prescribed for the air surrounding the relay under conditions, when the relay is mounted as indicated by the manufacturer

Storage Temperature

The ambient temperature range to which the current-carrying conductors are attached.

Operating Temperature

The ambient temperature range over which operation is specified with relays unmounted or mounted to a heat sink as specified.

Ambient Humidity

The specified humidity in which the relay can reliably work. It is generally expressed in relative humidity, “%RH”.

Vibration

This test is used to evaluate the resistance of the relay to heavy mechanical vibration leading to a permanent damage to the relay. This test is performed according to the IEC 60068-2-27, Ea test.

 

Shock

Functional: This test is used to evaluate the resistance of the relay to mechanical shocks such as those that could occur in transport or during operation with no opening of closed relay contacts with a duration of greater than 10µs. This test is performed according to the IEC 60068-2-27, Ea test.

Destructive: This test is used to evaluate the resistance of the relay to heavy mechanical shocks leading to permanent damage to the relay. This test is performed according to the IEC 60068-2-27, Ea test.

Unit Weight

Weight of relay.

Termination

Printed Circuit Board (PCB) or Quick Connect (QC).
